Passport facial checks fail to work with dark skin

When it launched a new passport checking service, the Home Office knew that it had trouble handling some shades of skin, a report in the New Scientist has revealed. The facial recognition technology failed to recognise the features of some people with very light or dark skin. The problem had become apparent during trials of the service. The government says that users can override the automated check if needed. Facial recognition maps a person's features from a computer-scanned image or live feed.
